Even when the seal projection is deformed due to fuel swelling or the like, sealing is enabled along the entire circumference thereof. High sealability is achieved even when the resin components are pressure-contacted with each other.

Abstract: The present invention generally comprises a floating slit valve for interfacing with a chamber. A floating slit valve moves or “floats” relative to another object such as a chamber. The slit valve may be coupled between two chambers. When a chamber coupled with the slit valve is heated, the slit valve may also be heated by conduction.

By disposing a low friction material spacer between the chamber and the slit valve, the slit valve may not rub against the chamber during thermal expansion/contraction and/or vacuum deflection and thus, may not generate undesirable particle contaminants. Additionally, slots drilled through the chamber for coupling the slit valve to the chamber may be sized to accommodate thermal expansion/contraction and vacuum deflection of the slit valve.
